The function of Cortex moutan

1. Cardiovascular effect: Cortex moutan can increase coronary blood flow, reduce cardiac output and reduce left ventricular work in anesthetized dogs. It has obvious protective effect on experimental myocardial ischemia and lasts for a long time, and reduces myocardial oxygen consumption at the same time.

2. effect on central nervous system: paeonol has antipyretic effect on fever induced by oral typhoid and paratyphoid vaccine and reduces body temperature in normal mice. Oral paeonol could inhibit the writhing reaction and tail tenderness response induced by intraperitoneal injection of acetic acid in mice, antagonize the hyperkinesia induced by caffeine, prolong the sleep time of mice induced by cyclohexobarbital sodium, disappear the righting reflex in mice at high dose, and obviously antagonize the convulsions caused by pentylenetetrazol, strychnine, nicotine and electroshock. The action site is in the reticular structure of the midbrain and thalamus.

3. Anti-inflammatory effect: intragastric administration of paeonol can inhibit the plantar edema caused by dextran or acetic acid or carrageenan in rats, and inhibit the enhancement of capillary permeability in mouse abdominal cavity or guinea pig skin induced by acetic acid or 5-hydroxytryptamine. Inhibit the occurrence of stress ulcer in mice.

4. Bacteriostatic effect: the experiment in vitro shows that the decoction of Cortex moutan has strong antibacterial activity against Bacillus subtilis, Escherichia coli, Typhoid, Paratyphoid, Proteus, Pseudomonas aeruginosa, Staphylococcus, Staphylococcus haemolyticus, Streptococcus pneumoniae, Vibrio cholerae and so on. Moutan leaf decoction has significant antibacterial activity against dysentery bacillus, Pseudomonas aeruginosa and Staphylococcus aureus, and its effective ingredient is Gallic acid.

5. Anticoagulant effect: in vitro experiment on human platelets, it was found that both water extract of Cortex moutan and paeoniflorin could inhibit platelet arachidonic acid to produce thromboxane A2, and then inhibit platelet aggregation. this is due to the inhibition of cyclooxygenase reaction from arachidonic acid to prostate H2. The methanol extract of Cortex moutan can inhibit the experimental thrombus induced by endotoxin.

6. effect on immune system: intragastric administration of paeoniflorin, paeoniflorin and benzoyl paeoniflorin could promote the clearance rate of carbon particles injected intravenously in blood. even if the function of monocyte-macrophage system was low, the phagocytic power of Kupffer cells in liver and macrophages in spleen were enhanced by microscope.

7. Effect on lipid metabolism: Cortex moutan and its paeonol, paeoniflorin can inhibit the fat decomposition of adipocytes induced by epinephrine, and the water extract of Cortex moutan can increase the production of glucose into fat in adipocytes, and significantly increase the production of fat caused by insulin.
